A new regular at Jersey City City Hall has visitors and even city staff doing double takes.

Hanging inside the rotunda between the second and third floors is a three-foot-tall head made of about 3,000 plastic bags, its eyes peering down at you as you enter the Grove Street municipal building.

The head, named Face and created by Queens artist Hui Seung Cho, is part of a group exhibition of Korean artists displayed on the second floor.

It startled Frank Maisonet, a police officer who guards City Hall.

“It scared the daylights out of me,” Maisonet said before taking a video of it to post on Facebook. “It’s amazing they can do all that with garbage bags.”

Installed yesterday, the giant head was certainly a conversation piece for City Hall workers, though some of the less artsy staffers were mystified.

“I don’t really get it,” one City Hall employee said in a whisper. “But I’m fascinated by people who can think up something like this.”

Bob Sommer, a mayoral advisor, saw Face for the first time today on his way through the rotunda. He called it "dramatic."

A look at Cho's portfolio shows a fixation with turning plastic bags and other unlikely materials into art. Superman, a six-foot sculpture, is stamped with logos for Pepsi, Dunkin' Donuts and Subway. It sells for $1,900.

Cho, 38, told The Jersey Journal that when he moved to New York City four years ago, he was struck by the sheer number of plastic bags he saw every day. He said looking at the bags that piled up in his home led him to meditate on consumption.

“Being able to consume more is considered happiness whereas not being able to the opposite,” Cho said in an email. “We so easily forget that every one of us will one day have to lose all that we seem to have earned, leaving behind our naked bodies like empty plastic bags.”

Face, which measures 35 by 70 inches, took about a year to complete. Cho said much of that time was spent collecting plastic bags of different colors.

The art exhibition, organized by the city Office of Cultural Affairs, will be on display in City Hall until April 30. There is an opening reception on Thursday, April 10 from 6 to 8 p.m.
